Prototype 2 gets souped-up pre-order move from GameStop

A new GameStop-exclusive pre-order bonus has been announced for Prototype 2. The extra is an in-game addition this time around, an enhanced move for protagonist Sgt. James Heller. The curiously named Bio-Bomb Butt Kicker ability is a tweaked version of the regular viral-powered Bio-Bomb move that players will be able to unlock during the course of the game. The upgraded attack will allow Heller to drop-kick infected enemies across the map, causing them to crash into or fall down on and damage enemies.

The bonus is only available for the 360 and PS3 versions of the game and will only be offered to pre-orders placed between January 1 and April 23.

Prototype 2 is slated to hit store shelves on April 24 for the 360, PC, and PS3.
